Hello! There are a lot of problems that arise on computers associated with various viruses and malware. And more and more often questions appear on the blog like I do everything according to the instructions, but nothing works, and when we start to figure it out, it turns out that often the problem is that the computer is full of all sorts of different viruses. And they, as a rule, create all sorts of problems and errors.

Therefore, I decided to write an article about how you can quickly scan your computer for viruses without even installing an antivirus. The only thing you need is an internet connection. I'll tell you how to use ESET online scanner Online Scanner You can scan your computer for various types of threats.

I think you know that an antivirus should always be installed on your computer, even a free one. You also need to update anti-virus databases from time to time, which become outdated very quickly. But you can install only one antivirus on your computer, and of course it will not be able to provide a hundred interest protection from viruses.

Therefore, if you have some kind of problem, and you suspect that a virus is to blame for this problem, then you should scan your computer with other antiviruses, or antivirus utilities, such as.

As I already said, you cannot install several antiviruses on your computer at the same time, and installing and uninstalling them one by one is also not a good idea. That's why ESET company created a service with which you can scan your computer for viruses without even installing an antivirus program, and we don’t need to create it either, although this is another good way remove viruses.

We just go to the site, launch the scanner and wait for the antivirus to check everything. This method has its advantages, for example, the scanner always uses the latest anti-virus databases. But if you have ESET NOD32 antivirus installed, then I think there will be little benefit from the ESET Online Scanner. It’s just the same company, and the databases are both online scanner and regular version antivirus, use the same ones.

At one time I saved the site folder in Goole Drive, so these files are still saved in cloud storage. In the cloud OneDrive storage The anti-virus scanner detected a threat in some keygen that was in the training course.

Greetings, dear blog visitors. Dmitry Smirnov is in touch with you as always, and in this article I want to tell you about how to check your computer for viruses quickly and freely, simply and affordably! In the last article I wrote about that, and now I’ll tell you about viruses!

How to check your computer for viruses

Using your favorite computer, after a certain period of time, you began to notice that the boot process began to occur more slowly, programs open and run with greater delay, or some of them stopped functioning, produce errors, and sometimes it seems that the system itself produces some - visible actions not ordered by the user.

It's time to check your computer for viruses online. And what exactly will we check for? There may be several main options:

1. Checking your machine's system disks;
2. Checking system files for viruses and malware;
3. Checking for the presence of unnecessary and unused files, programs, the contents of Internet browser folders, temporary file storage folders, etc.;
4. Compatibility check collaboration some programs.

This list, of course, is not exhaustive, but it lists, perhaps, all the main types of system checks available to the average user. We will not take into account users at the level of professional programmers, hackers, etc.

When we think about verification, we assume that we need special, complex and expensive programs to carry out this process. Agree, I don’t really want to spend time searching and money buying all sorts of incomprehensible software if it’s not at all clear what to check. I would like to note that an important feature of paid licensed software is the possibility of its regular updating, all possible support from the developers and the uninterrupted operation of its work and the presence of a large arsenal of various “fine settings”.

Free software can’t always boast of this, but there are quite worthy examples among it. Let's consider them.

1. Free check system drives a simple one will help standard program, contained in all latest versions Microsoft Windows environment.
   • Click Start, select Computer, a window appears indicating the drives. We move the cursor to required disk and press the right mouse button once. In the menu that opens, find properties and click.

In the same window, on the General tab, you can set disk cleanup and select categories of files that can be deleted as a result of the program. Do this with caution.

• On the service tab, find the Run check button and click it.

• By clicking Start, we force the system to start checking the selected disk. As a result of such a check, all system errors and checked, and damaged disk sectors were restored (if you check both boxes). The system may ask you to start scanning the next time you boot. This may take a few minutes, depending on the size and condition of your drive. This repair program can be scheduled to run on all drives in the system at once. Then when loading they will be checked in order of priority.

1. There are a lot of well-known and well-proven freely distributed versions antivirus programs and healing utilities that will analyze the system or specified individual parts of it for the presence of viruses, Trojans, worms and other “pests” of the system. Here are some of these programs.
   • Antivirus solution Avast Free, which is successfully used by about 230 million inhabitants of the Earth. You can download the program for free from the Russian-language website https://www.avast.ru/index. Of course, there are paid advanced packages of this antivirus, but we will talk about its free version.

• The developers will ask you to go through simple procedures.

• The program allows you to scan with a choice of parameters (viruses, outdated software, network threats, allows you to analyze system performance and suggest ways to optimize it. Of course, Avast Free will not save you from ultra-modern and complex viruses And malicious code, but for regular user Internet, it is quite suitable and you will like it because of its ease of download, interface, good and high-quality work.

• For example, intelligent scanning has been launched.

• And here are the results of this scan. You can eliminate everything in one fell swoop by clicking on the appropriate button.

2.6. Another excellent option for checking your system for viruses and malware is the free healing utility from Dr. Web – Cureit, available at http://free.drweb.ru/cureit.

2.7 Download this program, install and configure. It checks user-selected folders and drives for the presence of harmful “inhabitants” of the Internet. She will suggest actions with them (Quarantine-Cure-Delete). The distribution of the program increases with each release and is already about 200 MB.

A feature of the versions released in the last 2-3 years is that the program does not block the operation of the system during testing and allows you to download other applications and programs.

3.1. Program Total Commander will allow you to check the presence of unnecessary and unused files, programs, the contents of Internet browser folders, temporary storage folders for files, etc.;

This solution allows you to:

• Edit the list of startup programs;
• Remove installed programs;
• Clean the program registry;
• Clean system disks;
• Clean labels for a long time not run by the user.

3.2. For example, let's run Registry Cleaner.

There are other similar packages of treatment and testing utilities that allow you to “clean” the system, delete unnecessary and faulty files, and perform “ fine tuning systems”, etc. (eg Ace Utilities, Norton Utilities). But you need to use them with great caution, understanding exactly what you are going to delete and how this may affect the operation of the system.

1. There is a class of programs that allow you to understand the compatibility of various software installed on your computer. Here we will not consider such programs due to their complexity and the ambiguity of their results.

You can limit yourself to only a few rules so that your system does not become inoperable after installing the next program:

• If possible, do not install many programs of the same type of work on the disk (many cleaning programs, etc.);
• Do not install several antiviruses together on the disks of one machine (they most often perceive each other as macro viruses and can block the operation of the system. Then you will need to run it in safe mode and removing one of them;
• Do not install unverified, dubious programs.

Study the computer and its components, informatization is the future. It is the key to success in many industries. And now you know how to check your computer for viruses free and easy!
